Cell Membrane Quiz

The diagram illustrates the activity of vesicles during a cellular process.

Which statement best explains the function of the vesicles?

• Delivering packaged materials to the Golgi apparatus for protein synthesis

• Exchanging genetic information between the Golgi apparatus for protein synthesis

• Extracting portions of the Golgi apparatus to be regenerated for growth within the cell

• Transporting packaged molecules from the Golgi apparatus to be released out of the cell

Amoebas are one-celled organisms that live in water, mud, and in animals. These creatures have a flexible cell membrane filled with watery cytoplasm. The actions of the amoeba are directed by the nucleus. Contractile vacuoles store and discharge water. To move, the liquid cytoplasm streams to the edge of the cell wall and forms pseudopodia, or false feet. These pseudopodia surround the amoeba’s prey and engulf the food into a food vacuole where it is digested by enzymes.

Which structure of the amoeba plays the main role in maintaining homeostasis with its watery environment?

• nucleus

• food vacuole

• pseudopodium

• contractile vacuole

Diffusion and osmosis are both vital to cell function. Diffusion and osmosis are similar in that they are both types of –

• protein synthesis processes

• passive transport processes

• cellular replication processes

• cellular metabolism processes

Which of the following substances must be taken into the cell by the structure above labeled 3 because it is too large to pass through the cell membrane?

• sodium

• glucose

• polysaccharide

• potassium

The cell membrane plays an essential role in the life of the cell. How does the cell membrane help maintain the health of the cell in the figure above?

• The cell membrane contains genetic information of the cell.

• The cell membrane provides support and protection for the cell.

• The cell membrane is where protein molecules are manufactured in a cell.

• The cell membrane regulates the movement of materials in and out of the cell.

Explain the process illustrated in the diagram.

• passage of water molecules through a semipermeable membrane to equalize concentration

• movement of molecules against a concentration gradient expending energy

• separation of suspended particles from a fluid environment through a porous membrane

• transport of molecules across a membrane from a high to low concentration gradient by means of a carrier molecule

The picture shows a contractile vacuole of a uniellular freshwater organism. The contractile vacuole regulates flow of water into and out of the cell in an aquatic environment.

What condition causes the contractile vacuole to fill with water?

• The concentration of water is greater outside the cell than inside the cell

• The temperature of water in the vacuole is higher than the temperature of its environment

• The concentration of water inside the cell is the same as the concentration outside the cell

• The temperature of water in the vacuole is lower than the temperature of its environment

Some students used a vinegar solution to dissolve away egg shells and used the eggs as a models of human red blood cells.

Which statement best describes the role of the cell membrane in this model?

• A cell membrane is an impermeable barrier that prevents water from entering the cell.

• The cell membrane allows solutes to enter the cell, which causes the cell to shrink.

• The cell membrane allows water to enter and leave the cell

• The cell membrane removes solutes from the environment
